If A has 16 coins and b has 15 coins what is the probability of A getting more head?
CLUE: A has a higher probability.

Probability that A wins
$\sum_{i=1}^{16} \sum_{j=0}^{i-1} {16 \choose i} {15 \choose j} \left(\frac{1}{2} \right)^{31}$
Probability that B wins:
$\sum_{i=0}^{14} \sum_{j=i+1}^{15} {16 \choose i} {15 \choose j} \left(\frac{1}{2} \right)^{31}$
Probability for draw:
$\sum_{i=0}^{15} {16 \choose i} {15 \choose i} \left(\frac{1}{2} \right)^{31}$

75% I think.

If they both have 15 coins then it's 50%. Then you consider the 50% chance that you need the 16th coin, which has a 50% chance of breaking the tie in favour of A

A can pay more to a prostitute, so in case they are fighting over one A has more ressources to get rid of B or overcharge the girl that ought to give head.
